This prospective survey study investigates knowledge, attitudes, experiences, and practices related to dental care in patients with head and neck cancer among affected patients and dentists. Participants complete an anonymous online questionnaire before and after receiving written, guideline-based information. The study aims to evaluate whether targeted educational materials improve knowledge and perceptions regarding dental care in the context of head and neck cancer treatment.
Patients aged 18 years or older with head and neck cancer whose health status allows completion of a questionnaire
Practicing dentists in Germany registered in the OAK-Verlag address database
Lack of consent to participate
Insufficient German language skills that prevent completion of the questionnaire
Single group
Educational material,
Other interventionPatients with head and neck cancer and practicing dentists in Germany participate in an anonymous, prospective pre-post survey study. Both groups complete a baseline questionnaire assessing demographic characteristics as well as knowledge, attitudes, experiences, and decision-making related to dental care in the context of head and neck cancer treatment. Following the baseline assessment, participants receive group-specific, guideline-based written educational information. After reviewing the educational material, participants complete a post-intervention questionnaire with identical content. The effect of the educational intervention is evaluated by comparing pre- and post-assessment responses within each group.
Change From Baseline in Knowledge and Decision-Making Regarding Dental Care, Assessed by a Self-Administered Questionnaire (Percentage of Correct Responses)
Study outcomes are defined as the effects of the interventions measured using a self-administered questionnaire. Questionnaire responses are summarized as a percentage score ranging from 0% to 100%, with 100% indicating all responses answered correctly. For each research question, outcomes are calculated as the change (Δ) in percentage scores between pre-intervention (baseline) and post-intervention assessments.
